NEW TYPE OF AGGREGATE USED ON BANGOR PROJECT

A NEW TYPE OF AGGREGATE HAS BEEN USED IN THE BITUMINOUS MIX PLACED ON A SHORT SECTION OF ROAD IN BANGOR. THE MAN- MADE AGGREGATE IS WHITE AND WILL RESULT IN A LIGHT-COLORED ROADWAY ONCE TRAFFIC WEARS AWAY THE TOP LAYER OF ASPHALT. THE MATERIAL IS PRODUCED BY MELTING SAND AND LIME AND HAS BEEN TESTED IN PAVEMENT MIXES IN ILLINOIS AND MICHIGAN. THE MIX USED IN BANGOR WAS 30% OF THE WHITE AGGREGATE PLUS STANDARD AGGREGATE AND ASPHALT. TESTS INDICATE THAT PAVEMENT SURFACES CONTAINING THE NEW MATERIAL POSSESS ANTI-SKID QUALITIES AND AID IN VISIBILITY AT NIGHT. THIS LAST QUALITY WOULD SEEM TO MAKE IT USEFUL IN DELINEATING APPROACHING ROADWAYS AT INTERSECTIONS, THE RAMPS OF INTERCHANGES AND PEDESTRIAN CROSSWALKS. /AUTHOR/
